In 2017 we published the first MUSE spectroscopic survey data release [1]}, [2]} in the Hubble ultra-deep field [3]} area. These two papers were published together with eight other papers, providing a first glimpse into the richness of the data and their scientific impact. In that series of papers we investigated the photometric redshift properties of the sample [4]}, the properties of C iii] emitters [5]}, the spatially resolved stellar kinematics of galaxies at z=0.2–0.8 [6]}, the faint end of the Ly luminosity function [7]}, the properties of Fe ii\(^*\)  emission [8]}, the extended Ly halos [9]}, the evolution of the galaxy merger fraction [10]}, and the equivalent-width properties of \(\mathrm {Ly}\alpha \)  emitters [11]}.
